Contactless Energy and Data Transfer

The operating distance between label and reader antenna is typically up to 120 cm in an

appropriate gate configuration. The label antenna consists of a simple coil with a few turns.

Contactless labels are passive. The RF communication interface allows to exchange data with

26 kbit/s. This high data transmission rate permits short transaction times.

An intelligent anticollision function allows to operate more than one label in the field

simultaneously. The anticollision algorithm selects each label individually and ensures that the

execution of a transaction with a selected label is performed correctly without data corruption

resulting from other labels.

System Security

The serial number is unique for each label and can not be changed.
